    Can I use with 305 HO heads

    Asked by: Mandy
    The Sealed Power 844-H618CP piston will require checking at installation for clearance.

    Since this piston has a cutout around the spark plug location and a shallow dome can it be used with a Vortec style head?

    Asked by: Irian90
    No, this is not made for the Vortec cylinder head applications.
